To all whom 'it' may concern:

Be it'known that I, JOHN DIErz, a citizen ofthe United States, residing at Cincinnati, .in the, county of Hamilton and State of Ohio,

have 'invented certain-new and useful Imrovements in -VVater-Motors, of which the l :ollowin is a s ecication. v

Theo Ject o my invention is to provide a Water mot-or o'r' improved construction and' operation, which is especially adapted for driving light machinery, such as .washing machines.

My'invention. consists in the combination and arran ement of partsl hereinafter described an claimed.

In the drawings; Figure 1 is a horizontal section of a mot'r embodying my invention. Fig. 2 is an elevation of. the motor. Fig. 3 is a horizontal section through the valve. Fig. 4 is a section von line 4-4 of Fig. 3, and Fig. 5 is a. detail view of the valve operating mechanism. The iston rod of the motor is in the form of twopipes A and B secured to the piston head C as shown. In piston head C, surrounding the open mouths of pipes A and-B are openings c which serve to maintain pipes A and B in permanent open communication with lthe interior of cylinder D on opposite sides of piston head C. Flap valves E are secured to piston head C by rings @secured by screws e- At its inner side cylinder D carries. a rack bar F meshing with a gear G feathered to the shaft H, which may be connected with vthe operative parts of a washing machine or otherfliight machinery:

Pipes A and Biere supported by and con- Whic'h lare secured to the frame L of the'motor. Pipes M and N are securedto pipes il and K by means of removable couplings m and n and serve to connectpipes A and B with the chambers o and o2 in valve chamber O, as shown.

Supply and exhaust pipes P and Q commmate withchambers p and g inchamber 0,and admission and exhaust valves p and q are slidably mounted in chambers p yand g. The positions of valves p and g" which in the walls of chambers p and g aie made spider shaped as shown in Fig. 4, so that when the port at one end of a chamber is closed by its valve the port at the other end is open At one end the valves p and g are secured to a cross bar 1 by means of screwsor pins r which permit of some play or lost motion of bar 1.

bar 1'- is .carried by a rod R connected with a rod S slidably mounted onthe top of valve chamber O.' Near itscenter rod, S carries loose rings: or Washers s held from vmoving away from each other by pins s', andv imprisoning a spring s2.. On the bottom of cylugs d adapted-to contact with washers s at either end of the stroke of the cylinder. By this construction it will be seen that with valves'p and q in the positions shown in Fig. 3, water from supply pipe P will pass to chamber c in valve chamber O and thence' through pipes M and J to pipe A and enter the corresponding side of cylinder D, movin the-latter in the direction of the arrow in ig. 1. At the same time exhaustv ipe Q is in communication with chamber o2 'in valve chamber G, and thence through pipes N and K with pipe B, thus serving to exhaust the other side of cylinder D so as to permit of its movement. As the cylinder D nears ters the corresponding washer s, com ressing the spring e? and sliding rod S to shi t valves p and g so as to throw cation with pipes N an. and pipe g 1n cbmmumcation with pipes M-and yhis reverses the movement of cylinder D; the compression in the singley spring szrserves to securely seat valves p andq and to give the cylinder` an initial impulse on"its rcrturn stroke. Y l

By proviflingbetween cross bar r and screws r', the former is free to move back from the port m chamber p under the in-V fluence oi water-emerging therefrom on that side so as to permit free passage of the water without unseating the valve p, and thevalve is always Jfree to properly seat itself under the influence of the ,inrushing water, regardless of the position et the valve at the time the water is turnedon. The play or space be the end of its stroke, a lug d encouni e P in commumtween the end of the valve p and cross bar' 1'* 1 should be equal to the movement of the valve.

lt will be observed that the iston head forms a solid partition between t e operative and inoperative sides of the cylinder so that there can be no leakage., and the cylinder head carries no valves to create friction and resistance. The water emerging radially from openings c under valves E tends to seat and hold said valves in position. Furthermore,`by the above arrangement the cylinder and operative shaft are mounted centrally in their housings, so Athat the strains are borne equally by the two sides of the housing and the weight is evenly distributed on each sid of the operative shaft.

While lI have shown and described my device as ada ted to be operated by water, it will be un erstood that any other fluid under pressure may be used. I clalm: y
